In the present work a model is developed, which describes thedependence of the quadrupol enhancement on temperature and anisotropyof the chemical environment. This model is used to describe the Borrmannspectroscopy results obtained from a strontium titanate single crystal.Furthermore, the influence of the mosaicity of real crystals on thequadrupole enhancement is studied by means of simulations, which arebased on the dynamical theory of diffraction and a modified structuremodel of barium titanate.The method of diffraction anomalous fine structure (DAFS) is based onthe combination of X-ray diffraction and absorption spectroscopy and allowsinvestigating the local atomic structure of centrosymmetric crystalsutilising the additional selectivity due to diffraction. In the present workthe novel method of diffraction anomalous fine struture in Laue geometry(LDAFS) is developed. It utilizes the intensity of the Laue geometrydiffracted beam, which experiences an altered absorption due to the Borrmanneffect. Its experimental applicability is verified by experiments ona barium titanate single crystal and comparison with conventional X-rayabsorption spectroscopy results. 000418948 536__ $$0G:(DE-HGF)POF3-632$$a632 - Detector technology and systems (POF3-632)$$cPOF3-632$$fPOF III$$x0 000418948 693__ $$0EXP:(DE-H253)D-W1-20150101$$1EXP:(DE-H253)DORISIII-20150101$$6EXP:(DE-H253)D-W1-20150101$$aDORIS III$$fDORIS Beamline W1$$x0 000418948 693__ $$0EXP:(DE-H253)D-A1-20150101$$1EXP:(DE-H253)DORISIII-20150101$$6EXP:(DE-H253)D-A1-20150101$$aDORIS III$$fDORIS Beamline A1$$x1 000418948 7001_ $$0P:(DE-H253)PIP1001249$$aWeckert, Edgar$$b1$$eThesis advisor$$udesy 000418948 7001_ $$0P:(DE-H253)PIP1001227$$aWurth, Wilfried$$b2$$eThesis advisor$$udesy 000418948 8564_ $$uhttps://bib-pubdb1.desy.de/record/418948/files/Laurus_dissertation.pdf$$yOpenAccess 000418948 8564_ $$uhttps://bib-pubdb1.desy.de/record/418948/files/desy-thesis-18-043.title.pdf$$yOpenAccess 000418948 8564_ $$uhttps://bib-pubdb1.desy.de/record/418948/files/Laurus_dissertation.gif?subformat=icon$$xicon$$yOpenAccess 000418948 8564_ $$uhttps://bib-pubdb1.desy.de/record/418948/files/Laurus_dissertation.jpg?subformat=icon-1440$$xicon-1440$$yOpenAccess 000418948 8564_ $$uhttps://bib-pubdb1.desy.de/record/418948/files/Laurus_dissertation.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000418948 8564_ $$uhttps://bib-pubdb1.desy.de/record/418948/files/Laurus_dissertation.jpg?subformat=icon-640$$xicon-640$$yOpenAccess 000418948 8564_ $$uhttps://bib-pubdb1.desy.de/record/418948/files/Laurus_dissertation.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000418948 8564_ $$uhttps://bib-pubdb1.desy.de/record/418948/files/desy-thesis-18-043.title.gif?subformat=icon$$xicon$$yOpenAccess 000418948 8564_ $$uhttps://bib-pubdb1.desy.de/record/418948/files/desy-thesis-18-043.title.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000418948 8564_ $$uhttps://bib-pubdb1.desy.de/record/418948/files/desy-thesis-18-043.title.jpg?subformat=icon-700$$xicon-700$$yOpenAccess 000418948 8564_ $$uhttps://bib-pubdb1.desy.de/record/418948/files/desy-thesis-18-043.title.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000418948 909CO $$ooai:bib-pubdb1.desy.de:418948$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 000418948 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1006959$$aDeutsches Elektronen-Synchrotron$$b0$$kDESY 000418948 9101_ $$0I:(DE-H253)_CFEL-20120731$$6P:(DE-H253)PIP1006959$$aCentre for Free-Electron Laser Science$$b0$$kCFEL 000418948 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1001249$$aDeutsches Elektronen-Synchrotron$$b1$$kDESY 000418948 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1001227$$aDeutsches Elektronen-Synchrotron$$b2$$kDESY 000418948 9101_ $$0I:(DE-H253)_CFEL-20120731$$6P:(DE-H253)PIP1001227$$aCentre for Free-Electron Laser Science$$b2$$kCFEL 000418948 9101_ $$0I:(DE-HGF)0$$6P:(DE-H253)PIP1001227$$aExternes Institut$$b2$$kExtern 000418948 9131_ $$0G:(DE-HGF)POF3-632$$1G:(DE-HGF)POF3-630$$2G:(DE-HGF)POF3-600$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bForschungsbereich Materie$$lMaterie und Technologie$$vDetector technology and systems$$x0 000418948 9141_ $$y2018 000418948 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000418948 920__ $$lyes 000418948 9201_ $$0I:(DE-H253)FS-PS-20131107$$kFS-PS$$lFS-Photon Science$$x0 000418948 980__ $$aphd 000418948 980__ $$aVDB 000418948 980__ $$abook 000418948 980__ $$areport 000418948 980__ $$aI:(DE-H253)FS-PS-20131107 000418948 980__ $$aUNRESTRICTED 000418948 9801_ $$aFullTexts
